This is the Structure on FTP-Site of the Backupserver! Not locally where 
the Postmaster runs on!

Locally the Postmaster can create a basebackup (rcvry.rcv) then the 
FTP-Deamon logs on to the
Remote FTP-Backupserver and Uploads this File to keep it save:

/pg/backup/12_24_2008/
/pg/backup/12_24_2008/base/rcvry.rcv    <--- Basebackup

At the Next:
If a New Record at the Database was written, then the Postmaster locally 
creates

A change File named: "0001.chg"

After thits the locally FTP-Deamon transfers this File to

/pg/backup/12_24_2008/changes/0001.chg  <--- Changed Data

Then

/pg/backup/12_24_2008/changes/0002.chg  <--- Changed Data
/pg/backup/12_24_2008/changes/0003.chg  <--- Changed Data
....
/pg/backup/12_24_2008/changes/0010.chg  <--- Changed Data

Then the FTP-Backupdeamon merged the last 10.x  *.chg Files to one greater
*.RSF File "Online while logged into the FTP-Backupserver" and Delete Online
the Last 10 *.chg Files (after this the Last 10.x *.chg Files, created 
by the Postmaster
can be deleted localy where the Postmaster runs).

The Benefit:
If the Machine where the Database run on having a Mailfunction, then the 
Last Record
of the Databasecatalouge is backed up to an *.chg or *. RSF File.

Thadt my Idea of this
